Disagreement on rewards, and FWIW I generally only downvote a small or moderate amount, often less than the amount by which I believe it believe is excessive. I don't know which post you're talking about but I would guess the actual payout is still high (i.e. higher than 99% of all the posts on the platform, many of which are quite good and get little or nothing). Downvoting these outlier payouts shifts reward funds to lots of other deserving posts instead of just concentrating them at the top because of a few large stakeholders too lazy or apathetic to vote any other way.
